A Summary of Studies Addressing the Efficacy of Lead Abatement

It is expected that lead hazard interventions will both prevent further childhood lead exposure and produce positive health outcomes among children benefitting from the interventions. The extent to which the scientific literature supports this expectation is characterized. Currently available scientific information was compiled on the effectiveness of lead hazard intervention in reducing childhood lead exposure. The studies identified address the efficacy of intervention strategies employed to reduce childhood exposure to lead-based paint, and to elevated soil-lead and dust-lead levels. Results and conclusions from these studies are summarized and their implications are discussed.
